peer capability-advertise route-policy-distribute

Function

The peer capability-advertise route-policy-distribute command enables Routing Policy Distribution (RPD) on a BGP device.

The undo peer capability-advertise route-policy-distribute command restores the default configuration.

By default, RPD is not enabled on a BGP device.

Usage Guidelines

Usage Scenario

In the RR+ solution, the controller delivers BGP FlowSpec routes that carry the RPD attribute to forwarders. Upon receipt, forwarders convert those that have only the destination IP address specified to common IP routes to guide traffic forwarding. This implementation allows traffic to travel along the optimal path determined by the controller.

To enable a BGP device serving as a forwarder to support the preceding scenario, run the peer capability-advertise route-policy-distribute receive command.

Example
